Global energy transition investment hit a record $2.3 trillion in 2025, with electric transportation becoming the biggest driver.

Global Energy Transition Investment Surpasses $2.3 Trillion, with Electric Transport as the Primary Driver

BloombergNEF (BNEF) released its annual report "Energy Transition Investment Trends" in January 2026, showing that global energy transition investment reached a record $2.3 trillion in 2025, up 8% from 2024. Although the growth rate has slowed significantly from 27% in 2021, the absolute scale still hit a new record, indicating that the global decarbonization process remains resilient amid policy and trade headwinds.

Electric transport became the largest investment sector, attracting $893 billion in 2025, covering electric vehicles, charging infrastructure, battery gigafactories, and related supply chains. Renewable energy investment ranked second at $690 billion, but fell 9.5% year-on-year, mainly due to uncertainty caused by policy adjustments in China's electricity market. Grid investment followed closely at $483 billion, reflecting the urgent need to modernize global power systems.

Industry Background: Clean Energy Investment Exceeds Fossil Fuels for Two Consecutive Years

The report shows that clean energy supply investment (including renewables, nuclear, carbon capture, hydrogen, energy storage, and grids) surpassed fossil fuel supply investment for the second consecutive year in 2025, with the gap widening from $85 billion in 2024 to $102 billion. Meanwhile, fossil fuel supply investment declined for the first time since 2020, down $9 billion year-on-year, mainly due to reduced spending on upstream oil and gas (-$9 billion) and fossil fuel power generation (-$14 billion).

BNEF Deputy CEO Albert Cheung said: "The past year has shown that despite policy and trade headwinds, the global energy transition remains resilient and offers abundant opportunities for investors. As many economies seek to strengthen energy security and build local supply chains, clean energy investment will continue to rise, particularly in relation to demand linked to the global buildout of data centers."

Key Developments: Regional Divergence and Supply Chain Investment Landscape

Asia-Pacific continued to dominate global energy transition investment, accounting for 47% of the global total in 2025. China remained firmly the world's largest market with $800 billion in investment, but renewable energy investment saw its first decline since 2013. India's investment grew 15% to $68 billion. The EU grew 18% to $455 billion despite unfavorable factors, contributing the most to global growth. US investment grew 3.5% to $378 billion, despite the Trump administration's attempts to slow the pace of the energy transition.Clean energy supply chain investment (including new clean technology product factories and battery metal production assets) grew 6% in 2025 to $127 billion, driven mainly by growth in battery manufacturing and battery materials investment. China still accounts for the vast majority of global supply chain investment, and BNEF expects this situation to continue for at least the next three years. However, all segments of the clean energy supply chain are facing overcapacity pressure, and the downward trend in clean technology product prices is expected to continue.

Industry Impact: Electric Mobility Reshapes Value Chains, Grid and AI Become New Variables

Electric Mobility Creates a New Industrial Value Chain

Unlike the early clean energy transition, which focused mainly on electricity and power generation, transport electrification is affecting every link from mining and manufacturing to software and digital services. Electric vehicles, batteries, charging networks, and critical mineral processing have attracted unprecedented capital, giving rise to a new industrial value chain. Battery recycling and next-generation battery technologies (such as solid-state batteries) are becoming new investment hotspots, bringing transformation opportunities to mining, chemical, and materials companies.

Grid Modernization Becomes a Hidden Growth Engine

The report specifically points out that grid investment is the most important hidden growth area in the energy transition. Modern economies need reliable, flexible, and smart power networks to cope with the rising penetration of renewable energy and growing electricity demand. Countries are investing heavily in transmission lines, smart grid technologies, advanced substations, and digital energy management systems. Grid investment reached $483 billion, becoming one of the fastest-growing segments in the global energy transition, directly supporting the expansion of renewable energy and the deployment of EV charging infrastructure.

AI Demand Generates a New Energy Investment Cycle

The rapid expansion of AI applications, cloud computing platforms, and hyperscale data centers is creating unprecedented electricity demand. BNEF estimates that data center investment in 2025 will be about $500 billion, exceeding total solar investment and second only to electric transport investment. Technology companies are meeting sustainability commitments and ensuring reliable power supply through long-term renewable energy contracts and investment in energy storage projects. The convergence of digital transformation and energy infrastructure is becoming an important new driver of clean energy investment.

Industrial Decarbonization and Energy Security Strengthen the Investment Logic

Heavy industries such as steel, cement, chemicals, and oil refining account for a large share of global carbon emissions. As countries implement stricter climate policies and carbon pricing mechanisms, industrial decarbonization is becoming an important investment direction. Green hydrogen projects, carbon capture facilities, electrified industrial processes, and sustainable fuel technologies continue to attract growing investor attention. At the same time, many countries, for energy security reasons, are actively investing in domestic renewable energy to reduce dependence on imported fossil fuels, giving clean energy projects the attributes of strategic infrastructure.

Challenges and Risks: Slowing Growth and Structural ImbalancesDespite record total investment, the growth rate of global energy transition investment has slowed from 27% in 2021 to 8% in 2025. Renewable energy investment has seen a rare decline, mainly triggered by policy adjustments in the Chinese market. In addition, the overcapacity problem in the clean energy supply chain remains severe, putting sustained pressure on product prices and corporate profitability.

BNEF warns that if wind power manufacturing investment cannot increase substantially, it will be difficult to remain aligned with the net-zero pathway; and if capacity expansion in the battery metals sector falls below current expectations in the future, the sector may face long-term supply-demand mismatches. Venture capital investment in climate tech companies declined for the third consecutive year, while public equity financing and M&A activity showed signs of recovery — in 2025, climate tech companies raised US$77.3 billion through private and public markets, up 53% year-on-year; M&A transaction value reached US$99.1 billion, up 37% year-on-year, with acquisitions in the clean power and corporate building sectors driven by data center construction serving as the main drivers.
